我正在编写一个自定义的post_controller钩子.我们知道,codeigniter uri结构是这样的:

和我的代码:
function hook_acl()
{
global $RTR;
global $CI;
$controller = $RTR->class; // the class part in uri
$method = $RTR->method; // the function part in uri
$id = ? // how to parse this?
// other codes omitted for brevity
}

我浏览了核心的Router.php文件,这让我很困惑.
谢谢.
通常在CodeIgniter Hooks中,我们需要加载/实例化URI核心类以到达方法.
post_controller_constructor,post_controller...钩子,我们可以获取CodeIgniter超级对象并使用uri该类:# Get the CI instance
$CI =& get_instance();
# Get the third segment
$CI->uri->segment(3);

pre_controllerhook,我们无法访问CodeIgniter 超级对象所以我们必须手动加载URI核心类,如下所示:# Load the URI core class
$uri =& load_class('URI', 'core');
# Get the third segment
$id = $uri->segment(3); // returns the id

在这种方法中,您可以使用$_SERVER数组来获取URI段:
$segments = explode('/', trim($_SERVER['REQUEST_URI'], '/'));
$controller = $segments[1];
$method = $segments[2];
$id = $segments[3];
